Hi I'm working with AIX 6.1 I would like to ssh to a server without entering password ( to monitor something) but there's no way to do that by authentication keys, so I need to write a script which can ssh to that server without entering password ( no need to hide passsword in the script, just an user account to monitor ). Can someone help me please :(:(☹ ---

Use `ssh-keygen` . Google or seach within the forum for more details. ---

For security reasons, it would make sense to enable ssh and not enforcing plaintext passwords in scripts, as THAT is a higher risk, due to the passwords beeing readable by everyone! Specialy, since you want to ssh on your server... Just my 2 cents. ---

> [@bobochacha29](#): > > As I said above, the authentication keys doesn't work in this case ( actually it's because of the limit of the OS and some security reasons ) Ah, I missed that point. You mentioned there is no option to use those! What issues you facing? Apart from ssh-keygen, you can use `expect` . ---

Because of the limit of the OS version of the server ( which can not update to a higher version ) I want to ssh, I can not ssh without password to that server by an user account ( it requires admin account ). If I could done it, I would have done it already. So please stop talking about the ssh-keygen. :mad::mad::mad: ---------- Post updated at 04:51 AM ---------- Previous update was at 04:46 AM ---------- > [@clx](#): > > Ah, I missed that point.

Could you show me detail code, because I found some examples using `expect` , but it seems not work 😕😕😕. Thank you ---

Assuming that you are not using ssh at all, can I presume that rlogin would be allowed? You can grant (for a given user) the source addresses that can rlogin to it without further credentials being required. Does that offer an option? I would try to avoid expect if possible because of the risks and complexities that it introduces. Robin ---

FabOS version 7 has a feature allowing an admin account to import authentication key for any users, but FabOS 6 doesn't. In FabOS 6, an admin account can import authentication key for only itself. It means that if I connect to that SAN switch using ssh-keygen, I'll have to login directly to an admin account, and this isn't my choice. I just want to do this by an user account. Not using ssh-keygen means that each time I run the script, I have to enter the password. It's the problem I'm facing :(:(:(. ---

As i see in documentation, you can create a user with admin role for which you can use ssh keys. "The default admin user must set up the allowed-user with the admin role." I haven't done this myself, but i suspect that admin role for user will be able to fulfill your request regarding "monitoring somethings" Hope the helps. Regards Peasant. ---

As what I read. there's no option to do that in FabOS, admin is admin.
